R2.51 Penguins again In Chapter 8 we learned about the extra- ordinary depth and duration of the dives taken by penguins. In that chapter we modeled a re-expression of Heart rate with the Duration (min) of dives. The data also include the depth of each dive. Here is an analysis that incorporates both variables: LDHR Resid Response variable is: LogHeartRate R squared = 79.5% s = 0.0869 0.0 Variable Intercept -0.2 Duration(min) Depth (m) 0.2- a) What is an appropriate interpretation of the coefficient of Duration in this regression? Here is a partial regression plot for the coefficient of Duration: Coefficient 1.99213 -0.04510 0.000887 0 Duration (min) Resid b) Based on this plot, do you think the coefficient of Dura- tion is a good estimate of the relationship of Duration to (log) Heart rate in these penguins? Explain.

In that chapter we modeled a re-expression of Heart rate with the Duration (min) of dives. The data also include the depth of each dive. Here is an analysis that incorporates both variables: LDHR Resid 0.2 Response variable is: LogHeartRate R squared = 79.5% s = 0.0869 Variable Intercept -0.2 Duration(min) Depth (m) a) What is an appropriate interpretation of the coefficient of Duration in this regression? Here is a partial regression plot for the coefficient of Duration: 0.0- Coefficient 1.99213 -0.04510 0.000887 Duration (min) Resid b) Based on this plot, do you think the coefficient of Dura- tion is a good estimate of the relationship of Duration to (log) Heart rate in these penguins?
